Prometheus allows to have groups with no rules, so we should support
it in vmalert as well for compatibility reasons.
It is also allowed to hot-reload empty groups by adding or removing rules.

Do not store in memory the response from the last scrape per each target if -promscrape.noStaleMarkers option is enabled.
This should reduce memory usage when the scraped targets return large responses.
Previously, ID for alert entity was generated without alertname or groupname.
This led to collision, when multiple alerting rules within the same group
producing same labelsets. E.g. expr: `sum(metric1) by (job) > 0` and
expr: `sum(metric2) by (job) > 0` could result into same labelset `job: "job"`.
The issue affects only UI and Web API parts of vmalert, because alert ID is used
only for displaying and finding active alerts. It does not affect state restore
procedure, since this label was added right before pushing to remote storage.
The change now adds all extra labels right after receiving response from the datasource.
And removes adding extra labels before pushing to remote storage.
Additionally, change introduces a new flag `Restored` which will be displayed in UI
for alerts which have been restored from remote storage on restart.

This should make visible the set flags at flag.Visit(), which is used later for logging
and exporting the `is_set` label for these flags at /metrics page
Commit fixes potential race condition when group update
and generating of ID() happens simultaneously.

Regression was introduced during code refactoring. It potentially
could lead to situation when SIGHUP signals were ignored while
vmalert was still busy with initing group manager.

The following errors:

The extra `/` may cause issues when additional path prefixes
are configured. Also, removing it makes it consistent
with the rest of declarations.

vmctl: properly convert influx bools into integer representation
When using vmctl influx, the import would fail importing boolean fields
with:
```
failed to convert value "some".0 to float64: unexpected value type true
```
This converts `true` to `1` and `false` to `0`.
Fixes#1709
